Mice and rats leave droppings, urine and nests in attics, crawl spaces, garages and walls. Rodent droppings cleanup safely removes the contamination, which can carry diseases including hantavirus in some areas, and replaces soiled insulation.
Professionals wet the droppings before removal, as the CDC advises, rather than sweeping or vacuuming them dry, and they use respirators in enclosed spaces.

What affects the cost
Sifixit does not quote prices, because every job is different. These are the things that move the price up or down, so you can compare quotes fairly:
- Area of attic or crawl space affected
- Insulation removal and replacement
- Access and height
- Number of nests

Insurance
Insurance usually excludes rodent damage as a maintenance issue. Some policies cover sudden damage, such as chewed wiring that caused a fire.
Licensing by state
Rules differ a lot between states. Here is who licenses this work in the states Sifixit covers most. Always ask for the license number and check it with the state.
- Most states do not license biohazard cleanup companies, so ask about bloodborne pathogen training, insurance and how they dispose of waste.
- California requires trauma scene waste management practitioners to register with the state.
- Florida regulates biomedical waste handling through the Department of Health.
